John is a software architect who builds software to help hospitals ensure patient care is evidence-based. He explains that software tracks user behavior on websites to test hypotheses and make decisions through A/B testing, comparing user behavior between two versions of a site. John also discusses how technology works in binary and encourages becoming a technologist with IoT expertise, and that engineering is about applying knowledge creatively to make things for others.

2. Hi!
 I’m John, Julia and Grace’s dad.
 I’m Software Architect
 I build software that helps hospitals ensure that patient care is evidence based.
 What is software?
 What is evidence?

3. Science
 Don’t guess, know.
 If you use the internet you are the subject of experimentation.
 Web sites track everything you do
 Hypothesis
 If the website did {something different} then {users and/or company} would receive {some
benefit}.
 A/B Testing
 Some users see version A
 Other users see version B
 The people running the site then make decisions based on where you go, how long you stay
and what you buy.

4. Technology
 There are 10 types of people in the world: Those who understand
technology and those don’t.
 In the binary language of computers 10 is two
 00
 01
 10
 11
 Be a Technologist
 Strive for Expertise
 IoT

5. Engineering
 It’s not who you know or what you know, it’s what you can make with what you
know for who.
 Engineers are makers
 Be original
 Fail fast

6. Math
 Statistics/Analytics
 Big Data
 Machine Learning
